To all whom it may concern:

.of said working parts.

' Be it known that I, MoRITz HEINEMANN, a subject of the King of Prussia, German Emperor, and a resident of Bielefeld, in the Province of Westphalia, Kingdom of Prussia, German Empire, have invented an Improved Machine for Securing in Position the Bottoms of Pasteboard Boxes and the Like, (patented in Germany December 5, 1894, No. 88,354,; in Austria June 12, 1896, No. 46/2371, and in England May 15, 1896, No. 10,439,) of which the following is an exact specification.

This invention refers to machines for securing in position the bottoms of pasteboard boxes and the like by means of a strip of gummed paper or serrated sheet metal that is pressed upon the rims of the bottom and the pasteboard ring by a roll or rolls of suitable shape. My improvements in machines of said kind relate to certain combinations and arrangements of parts, as are more fully described hereinafter, and the purpose of my improvements is to effect the union of the bottom and the ring in a quick and reliable manner by very simple mechanisms.

In order to make my invention more clear, I refer to the accompanying drawings, in which similar letters denote similar parts throughout the different views,and in which- Figure 1 is a side view of myimproved machine. Fig. 2 is a front view of the same, the foot of the frame being broken away. Fig. 3 is a rear view of the machine. Fig. 4 shows the main working parts, together with the united pasteboard parts, on an enlarged scale. Fig. 5 shows a modified form of construction Fig. 6 represents an other form of construction. Fig. 7 is a side View of amodified form of construction of the whole machine, some parts being in section. Fig. 8 is a front View of said machine, the disk S being in section and the lower portion of the pasteboard. box Z being broken away; and Fig. 9 is a bottom View of the disk S aforementioned.

Referring to Figs. 1 to 3, G designates the frame of the machine, the upper horizontal arm G of which consists of two parallel parts, holding between them an arm R, with a grooved roll P P. A spring T presses said arm against a screw T, that is supported in the downwardly-extending front end of the arm G and is provided witha head T. The roll'P,with its groove P,(which latter is rectangular in section,) may thus be raised or lowered by turning the screw T or the head T in one or the other direction.

The pasteboard ring Zto be provided with a bottom B is supported by a comparatively thick horizontal shaft Q, that is held by its reduced portion Q in the frame G and is furnished at its rearwardly-projecting end with a cog-wheel Q The shaft or cylindrical support Q may, if desired, be supported itself by a bracket G.

If a bottom is to be secured to a pasteboard ring, the arm R is moved off the support Q by means of the screw T T and the spring T and the pasteboard ring Z is then shoved upon said support. The bottom B is then placed against the edge of the ring Z, and thereafter the arm R is again lowered so as to bring the roll P down upon the two parts in question and clamp one to the other by means of its groove P. One end of the strip of gummed paper or serrated sheet metal is then brought under the roll P or into the groove P, respectively, and that end is fixed in positiongby slightly turning the roll P, so as to press said end upon the parts 13 and Z, thus initiating the union of these parts. The support Qis now rotated by the influence of any suitable mechanism upon the cog-wheel Q and I wish it to be understood that I do not confine myself to operating the support Q by cog-wheels or any sort of toothed gearing, as it will be clear to every expert that wheels or ropes may as well be employed and that a treadle or the like may be used for receiving the driving power proper. The cylindrical support Q while thus being rotated rotates in its turn the pasteboard ring Z and rotates by the mediation of the grooved roll P P (which in its turn is rotated from the pasteboard ring Z) the bottom B too. L in Fig. 4

designates such a strip that is already fixed to the bottom B and the ring Z or connects already said two parts, respectively. The strip L may be employed in pieces of suitable lengths, just as required for the circumference of the (round or oval) box, on it may be drawn off a roll which it has been wound upon.

The support Q need not indispensably have a horizontal position, but it may, if desired, be arranged vertically, as shown in Fig. 5. The mechanisms for operating and supporting the parts Q and P are in all material respects exactly the same as aforedescribed, and I think I may abstain from giving a more detailed description of said. modified form of construction, as the latter is most certainly clear to every one versed in the art in question.

In the second modification (shown in Fig. 6) the support is formed by a roll Q the circumference of which is formed into a wedge in such a manner that the wedge is able to fill up the groove P of the roll P at the place of contact of said parts Q and P. The manner of operation is also in this form of construction just the same as aforedescribed.

The pasteboard ring Z and the bottom B need not in any case be rotated, but may as well remain stationary upon astationary support. In the modified form of construction of the machine shown in Figs. 7, 8, and 9 the support 6,), which in this case is formed bya circular or oval disk, is stationary and is held from the adjustable or movable arm Q by the mediation of a short column Q. The arm Q may be turned around the main column G of the frame so as thereby to enable the pasteboard ring, as well as the bottom, to be put upon or removed from the supporting-disk Q The arm Q is supported from the main column G by means of a collar G made integrally with said column. The boss of the arm Q consists of two semicircular parts Q Q, one of which is made integrally with the arm Q whereas the other part forms a separate piece and is connected with the first part by bolts Q The roll P, however, instead of being stationary, as in the forms of construction aforedescribed, may be caused to revolve around the adjacent rims of the parts B and Z, and to enable said roll to move in such a way it has its bearing situated in a disk S, the axle A of which is held by the upper horizontal arm G2 of the frame G. The disk S is a frictional disk and is driven from a similar disk F, that is secured to a horizontal shaft 0, having its bearing in the frame G The shaft G is further provided with a fixed pulley and is arranged in such a manner that it may longitudinally be displaced for a short way, so as to be able to be pressed against or to be removed from the frictional disk S. To effect said longitudinal displacement of the shaft 0, the rear end of the latter is furnished with two collars 0 0 between which takes the vertical arm of a bell-crank lever D that is held by a bracket D secured to the frame G. The horizontal arm of said bell-crank lever is connected to a treadle D by means of a rod D, and said treadle is connected with a spring E, that constantly tends to move the disk F off the disk S.

The lever B, holding the roll P, is movably attached to a slide K, that may radially be displaced within the disk S, between two guide-ledges s. The slide K is connected by an arm K with a projection K that takes through a suitable radial slot of the disk S in such a manner that said projection extends over the upper surface of said disk. This disk is provided with a projection K arranged at the periphery of the same in. front of the projection K and serves as a bearing for a threaded spindle K, that runs through the projection K K is turned by any suitable means, the projection K and with it the slide K, will be radially displaced within the disk S, so as thereby to bring the roll P against and upon the adjacent rims of the pasteboard parts B and Z. To press said roll upon said parts, I make use of a threaded spindle T, that is held in a projection 21, having no thread, extending downward from the side ledges s, and is furnished at its free end with a nut T, that is formed into a hand-wheel and serves for moving the spindle T in longitudinal direction. The connection between the spindle T and the lever B is effected by means of a link T Having thus fully described the nature of my invention, what I desire to secure by Letters Patent of the United States is 1. In a machine for securing in position the bottoms of pasteboard boxes and the like, the combination with asupport for adjacent portions of the bottom and the pasteboard ring, of a grooved pressure-roll having an inclined position with regard to the plane of said bottom, and being adapted to press simultaneously upon both said adjacent portions, and means for allowing of the box being acted on upon the whole of its circumference by said pressure-roll, for the purpose as described.

2. In a machine forsecuring in position the bottoms of pasteboard boxesand the like, the combination with a rotatable support for adjacent portions of the bottom and the pasteboard ring, of a grooved pressure-roll having an inclined position with regard to the plane ofsaid bottom, and being adapted to press simultaneously upon both said adjacent portions, for the purpose as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
